Abstract (en)

It is provided a computer-implemented method for designing a CAD modeled object. The method comprises displaying at least one parametric three-dimensional shape; user-interacting with the screen; defining on a support a stroke corresponding to the user-interacting; computing at least one geometrical characteristic of the stroke; determining at least one parameter of a geometrical CAD operation based on the computed geometrical characteristic. Such a method makes the design of a CAD modeled object easier.
